<div>Hi,</div> <div>Thanks for your suggestion, I added SO_REUSEADDR and bind.. something in function gst_multiudpsink_init_send yesterday and it works. I think it's better to add a source port property for it in future. To set the sender's source port freely in udpsink is quite useful especially in some P2P applications, for NAT stuff. </div> <div> </div> <div>Regards,</div> <div>Yang  </div> <div>On 9/17/07, SP GLE <<a onclick="return top.js.OpenExtLink(window,event,this)" href="mailto:spglegle@yahoo.fr" target="_blank">spglegle@yahoo.fr</a>> wrote: <blockquote class="gmail_quote" style="PADDING-LEFT: 1ex; MARGIN: 0px 0px 0px 0.8ex; BORDER-LEFT: #ccc 1px solid">May be you can pass a file descriptor with the 'fd' property. To manage RTP you will probably have to manage RTCP, so two contigous port numbers. Using external fd throught udpsink you are able to do that.
